Company Profile



  1. Talk about noise from the motor, talk about the motor from the noise!
    Noise is a very important performance indicator of motors. Especially nowadays, people pay more attention to environmental factors and health factors. Motor noise has become a common concern of customers and motor manufacturers. For noise, most people, including us who are engaged in motors, are only a perception, but a deep understanding of noise may not be clear to everyone. We all know that the unit of measurement of motor noise is decibels, but how does the decibel come from? Ms. Shen will communicate with you through 2 tweets. Objectively speaking, the knowledge and knowledge covered by the motor is really worth our visit. scrutinize.

    The vibration of the object is the source of the sound, so to study the noise generated in the motor, it is necessary to study the vibration related to the source of the noise. Ms. Chen focuses on the magnetic fields that cause electromagnetic noise, the exciting forces they produce, and some measures to prevent noise during design.
    Motor noise classification

    The electromagnetic noise, ventilation noise and mechanical noise generated in the motor and their main vibration sources are summarized and discussed appropriately.

    The source of electromagnetic noise is the vibration and resonance in the iron core and its associated mechanical components caused by the alternating electromagnetic force caused by the various harmonic magnetic fields in the air gap of the motor. Mechanical noise is the periodic or aperiodic mechanical shock or vibration generated by the friction between the motor-related components.

    Aerodynamic noise includes broadband noise, whistle and whistle. Broadband noise is the noise generated by the rotation of the structural parts in the gas, and the gas is disturbed by the eddy current; the whistle is the noise generated by the relative movement between the stator and the rotor; the whistle is the noise generated by the resonance interference in the gap, the whistle Sounds and whistles are due to periodic fluctuations in the gas.

    what is noise

    From a physical point of view, noise is a combination of many incongruent or irregular residual sounds. Noise not only affects people’s work and rest, making people irritable and annoying; it even damages the health of guests, and even makes people deaf or cause many other diseases. At present, industrial noise has become 1 of the 3 major public hazards (sewage, waste gas, and noise) that pollute the environment. With the development of industry, in order to ensure a proper working environment and people’s health, certain measures must be taken to reduce the noise to an acceptable level. within the limit.

    The market demand for low-noise motors is actually a best example of our environmental protection and improved lifestyle. Once Ms. participated in a motor manufacturer, and the electromagnetic noise of the motor tested was particularly severe. Within 10 minutes, 2 people in the same group felt motion sickness. For noise, especially under the conditions of good motor operating environment, people began to pursue low-noise and high-efficiency motors, which is indeed a great progress in society.

3 phase motor

What are the key components of a typical 3-phase motor?

A typical 3-phase motor consists of several key components that work together to convert electrical energy into mechanical energy. Here’s a detailed explanation of the key components of a typical 3-phase motor:

  • Stator: The stator is the stationary part of the motor and contains the core, windings, and other structural components. It consists of a laminated iron core with slots where the motor windings are placed. The stator windings are connected to the power supply and create a rotating magnetic field when energized.
  • Rotor: The rotor is the rotating part of the motor and is located inside the stator. It consists of a laminated iron core with conductive bars or coils embedded in it. The rotor is designed to rotate within the magnetic field generated by the stator windings. The interaction between the stator’s rotating magnetic field and the rotor’s conductive elements induces currents in the rotor, creating a torque that drives the rotation of the motor.
  • Windings: The windings are conductive coils of wire that are wound around the stator slots. In a 3-phase motor, there are typically three sets of windings, each spaced 120 degrees apart. These windings are designed to carry the three-phase alternating current (AC) from the power supply. The arrangement and connection of the windings create a rotating magnetic field in the motor, which interacts with the rotor to produce torque and rotation.
  • Power Supply Connections: The motor has terminals or leads for connecting it to the three-phase power supply. The power supply connections are typically labeled as L1, L2, and L3, corresponding to the three phases of the power supply. These connections provide the alternating current required to energize the stator windings and create the rotating magnetic field.
  • Bearings: Bearings are used to support the rotor and allow it to rotate smoothly within the stator. The motor typically has two bearings, one at each end of the rotor shaft. These bearings reduce friction and enable the efficient transfer of rotational motion from the rotor to the motor’s load.
  • Shaft: The shaft is a cylindrical component that extends from the rotor and serves as the mechanical link between the motor and the load. The shaft transfers the rotational motion generated by the motor to the connected equipment or machinery.
  • Housing or Frame: The motor is enclosed in a housing or frame that provides protection and support for the internal components. The housing is typically made of a durable material such as metal or plastic and is designed to withstand the operating conditions of the motor.
  • Cooling System: Many 3-phase motors incorporate a cooling system to dissipate heat generated during operation. This may include cooling fins on the motor housing, fan blades attached to the rotor shaft, or a separate cooling fan. Efficient cooling is essential to maintain optimal motor performance and prevent overheating.

These are the key components of a typical 3-phase motor. Each component plays a crucial role in the motor’s operation, from generating the rotating magnetic field to transferring mechanical energy to the load. Understanding these components is essential for troubleshooting, maintenance, and proper operation of 3-phase motors.
